Hot water comfort
GENERAL
This function provides the opportunity to control additional
heat in the tank, mixing valve and hot water circulation.
ADDITIONAL HEAT IN TANK
If an immersion heater is installed in the tank, it can be per-
mitted to produce hot water at the same time as the heat
pump prioritises heating or cooling.
MIXING VALVE
A temperature sensor reads the temperature of the outgoing
hot water to the domestic hot water and adjusts the mixing
valve from the water heater until the set temperature has
been reached.
HOT WATER CIRCULATION (HWC)
One pump can be controlled for the circulation of the hot
water during selectable periods.
